If it takes 10 seconds for 10 printers to print out 10 pages of paper, how many seconds will it take 50 printers to print out 50
Fed [463]

Lets use the formula RWT=J to solve this, where,

  • R is the rate
  • W is the number of workers/things
  • T is time
  • J is number of jobs/things

<em><u>"If it takes 10 seconds for 10 printers to print out 10 pages of paper"</u></em> - here -

W is 10 printers, T is 10 seconds,  and J is 10 pages. We can write:

R(10)(10)=10\\R(100)=10\\R=\frac{10}{100}\\R=0.1


<u><em>"how many seconds will it take 50 printers to print out 50 pages of paper"</em></u><em> - here we use R=0.1 (previously found) to figure out T.</em>

<em>RWT=J\\(0.1)(50)T=50\\5T=50\\T=\frac{50}{5}\\T=10</em>

So it will take 10 seconds for 50 printers to print 50 pages.

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.
Yanka [14]

Answer:

The sum is t.

Step-by-step explanation:

Consider the provided information.

The given expression are - 10t and t - 10t

We need to find the sum of the opposite of -10 t and t - 10t.

The opposite of -10 t is 10 t.

10t+(t-10t)

Remove the parenthesis.

10t+t-10t

Simplify the number

10t-10t+t

Use Additive inverse.

t

Hence, the sum is t.

Yao Xin puts 3/10 liters of potting soil in each pot for planting flowers. She has 5 2/3 liters of potting soil. How many pots c
Korvikt [17]

Answer:

18 8/9 pots

Step-by-step explanation:

Total potting soil = 5 2/3 liters

Potting soil per pot = 3/10 liters

How many pots can Yao Xin fill?

Number of pots Yao Xin can fill = Total potting soil / Potting soil per pot

= 5 2/3 liters ÷ 3/10 liters

= 17/3 ÷ 3/10

= 17/3 × 10/3

= (17*10) / (3*3)

= 170/9

= 18 8/9

Number of pots Yao Xin can fill = 18 8/9 pots

A cheetah ran 300 feet in 2.92 seconds. What was the cheetah’s average speed in miles per hour? Show your work.
Alchen [17]
You would divide the cheetahs distance which is 300 feet  by the cheetahs time which is 2.92 seconds 
distance÷time 
300÷2.92= 102.7 seconds or 103 seconds if you round up 
the cheetahs speed is 102.7 seconds or 103 seconds
